I assumed you meant automated stepping. If you mean just digital data, then
its Shull and Wollan in the late 1940's. Neutrons were always digital of
course; we had film and cameras much later than for x-rays.
You must be younger

Neutron diffractometers were automatic well before x-ray diffractometers,
and were also first for position sensitive detectors (PSDs) and of course
Rietveld refinement. Paper tape control was introduced in the 1950's,
computers in the early 1960's and PSD's in the early 1970's. X-rays

Jim,
\What do you mean by automated? Controlled by a computer with (presumably)
stepping motors? Robot sample changer?

Hi all,
Anyone know when/where the first automated powder diffractometer was
commissioned? I'm going to presume it was used with a non-laboratory source:
2nd, when/where was the first lab diffractometer commissioned?
